U-nderstand

Understand what the interviewer is asking for by using test cases and questions about the problem.

  • Will the input string ever be empty?
    • Yes, your code should allow for this.

P-lan

General Idea: Slice the entire string in reverse order.

1) Return a slicing of the entire input string, but with a negated step parameter

I-mplement

def reverse_string(myStr):
	return myStr[::-1]

# OR

def reverse_string(myStr):
	reversed_str = ''
	for char in myStr:
		reversed_str = char + reversed_str
	return reversed_str
